Bug 1504093 - Make DocumentResizeEventListener::HandleEvent() call public methods of HTMLEditor r=m_kato

DocumentResizeEventListener::HandleEvent() calls protected method,
HTMLEditor::RefreshResizersInternal().  However, this method is an event
handler, i.e., called when the editor is not handling an edit action.

Therefore, for ensuring AutoEditActionDataSetter instance, it should call
public method, nsIHTMLEditor::RefereshResizers() instead.
